chrome r433327 which is 73b3a441a128d14c81bed7afc981d35f0f401f1d (from Friday).

That contains chromite 2838d2b712a95224d7d9a84100891c45deb238f5 (from November 4) which supposedly includes a CL to fix this and a revert. See https://bugs.chromium.org/p/chromium/issues/detail?id=656726

chrome_util.py is still looking for *_manifest.json: https://chromium.googlesource.com/chromiumos/chromite/+/master/lib/chrome_util.py#381

Deleting that line seems to work. However, there may be other cleanup to do here. (For example, it would be nice to delete all the Envoy stuff.)

Note that Chrome won't start correctly even with this fixed: "black screen is  crbug.com/665544  which is another issue. DRM is finding 0 displays."
